CHAPTER 4: Operation

4.2 Switching Manually With the Keypad

To switch a given output to display a given input (or to blank an output), press “[out][.][in][Enter]” on the Switch’s keypad, where:

•[out] is the number of the output channel (1 through 4, or “*” for all outputs);

•[.] is the keypad’s decimal-point/Delete key;

•[in] is the number of the input channel (1 through 4, or 0 to blank the output); and

•[Enter] is the keypad’s Enter key.

For example, to display input #1 on output #3, press [3][.][1][Enter]. To blank output #2 so that it doesn’t display anything, press [2][.][0][Enter]. To send input #4’s video to all outputs, press [*][.][4][Enter]. Remember that any number of outputs can be switched to display the same input, but no output can be switched to display more than one input at the same time.

After you press each key, you have five seconds to press the next one; if you wait longer than that, the switching command is aborted. If at any time you press an invalid key or a key that the Switch isn’t expecting, the command is also aborted. For example, if you press [4], and then [.], but then press [5], or [.] again, or any unused key, the command in progress is discarded and the Switch resets itself.

Figure 4-2 shows a block diagram of the Matrix Video Switch if output #1 is switched to input #2, outputs #2 and #3 are switched to input #1, and output #4 is switched to input #3. (The “/ 5”s represent the five video signals on either side.)
